No two sign & banner jobs are alike; the different customizations available today are almost endless. Customers can now select from various materials, including vinyl, fabric, and mesh, reinforced edges, different types of print options, fastener finishes, and even material thickness. To meet changing customer demands, Stimpson® manufacturers and supplies long-neck self-piercing grommets & washers in addition to our regular length self-piercing grommets for materials up to ½” thick. Let’s explore the benefits of Stimpson XL length grommets for thick material and how they can save sign & banner professionals time and money. 



XL Length Self-Piercing Grommet & Washer Benefits:

  • Designed for Materials Up to a ½” Thick: Since Stimpson’s extra-long self-piercing grommets & washers feature an additional 3/10 of an inch L.U.F., they are ideal an ideal fastening solution for materials up to a ½ an inch thick, including corrugated plastic, vinyl, coroplast, woven polyester, fabric, foam board, gatorboard, and more.
  • Heavy-Duty Base Metal Options: Stimpson offers brass and 304 stainless steel base metal options for regular and extra-long-self-piercing grommets & washers. Standard and extra-long brass grommets are manufactured from heavier gauge brass to withstand indoor & outdoor applications for years to come.
  • Does Not Compress or “Squish” the Material: Experienced and inexperienced press operators have inadvertently compressed or “squished” the sign & banner material during fastener installation. Since additional setting force is not required, long neck self-piercing grommets & washers prevent accidental compression and damage to materials due to their additional length, saving time and money.
  • No Hole Needed: Similar to Stimpson’s regular length self-piercing grommets & washers, extra-long grommets pierce the material and set the grommet in one single action, immediately improving productivity when set with the iconic 405 bench press.
  • Attractive Appearance: Brass & stainless steel grommets retain their attractive modern appearance after installation and instantly enhance the aesthetic of any sign or banner.
